Resolving Condensation Problems

Condensation can be a real problem even with new window installations.

Tracking down the cause is often the key to resolving the problem. This largely involves identifying sources of humidity like cookers, washing machines, showers and baths, all of which can generate significant quantities of water vapour. Humidity emitted by these sources, dissipates out of the air onto cold surfaces such as windows. It is also worth noting that water vapour can also rise from the foundations of your home, but this is usually dealt with by a Damp Proof Membrane (DPM) which seals the lower part of supporting walls from rising water penetration (Check that your house has this and that it is in no way damaged or defunct). The principal solution to all of this is sufficient ventilation via extractor fans and air bricks in the areas where humidity levels are at there highest. 

If you have a pretty steadfast condensation problem then it’s important to keep tabs on the problem. This can be done with a hand held hygrometer which will enable you to track the peak times and worst affected locations. This will ultimately aid you in identifying the root cause of the problem.

Rotten timber windows can in themselves absorb lots of water, releasing humidity into the internal environment. The obvious remedy in this instance is good quality replacement windows, in particular double glazing which can help minimize condensation into the long term and also save energy costs to boot.

If all else fails it maybe worth asking a qualified damp and condensation expert to take a look, although you may kick yourself at the simplicity of the problem and solution. Taking note of the above points will help.
